Hello, I've been vegan for 2 years now with no problems, but for the past 3 weeks I've been having constant headaches throughout the day, always feeling bloated, and gassy. I thought that something in my diet was making me bloated and gassy and that it might be the cause of my headaches. My diet has been pretty consistent since the beginning which is : oatmeal with fruit in the mornings, more fruit with nut butters for lunch, starches and vegetables for dinner. I get more than enough calories throughout the day and I don't seem to be missing anything according to chronometer (except b12). Ok, so what I do for B12? I take liquid spray methylcobolomin and recently I started vaping it. Cutting out soy greatly reduced gas, but that's about it. The headaches are what's bothering me the most. It goes on for the entire day and the only way I can make it better is by riding my bike or do cardio. If anyone else has felt like this I'd like to know how you fixed it. Thanks.
